MARKING-PEN.

Patented Dec. 25, 1906.

To all whom it may concerit:

Be it known that I, GEORGE WILLIAM Lov- ERI NG, a-citizen of the United States, residingin the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in -Marking-Pens and I do declare the following to be a full,

' clear, and exact description of the invention,

such'as will enable others skilled in the art to which it appertains to-make and use the same, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form' a part of this Specification.

This invention relates to improvements in marking-pens, and more particularly to that class of marking-pens arranged to receivea large supply of ink and adapted for heavy shading and marking. Its object is to pro-. duce apen for the purposes as above outlined which is rigid in construction, may. readily be I v cleaned, in which the flow of ink is easily controlled, and with which a sharp and clean-cut line is always maintained.

To, that end it consists of a sheet-metal body portion in which a removable plate is fitted, forming a tapering reservoir for the reception of the ink and having an elongated i 1 opening atits edge'for the flow of the ink.

The invention further consistsin the de- Y tails of its construction and combination of its operative parts, all of which I will now proceed-to definitely describe and then point out vention and mountedin a holder.

tion of the same.

in the claims that whichI believe to be novel. In the drawings, Figure 1 is a perspective view of a pen arranged according to my in- Fig. 2 is an enlarged view showing the pen in side elevation. Fig. 3 is a central longitudinal see- Fig. 4 is a front face view of the pen. Fig. 5 is a rear face view. Fig. 6 is a cross-section of the same, taken through the line 6 6, Fig. 3. Figs. 7 and 8 are views same parts in all the views.

showing modified forms of my invention.

' The same reference characters indicate the Let the numeral 5 represent the pen in its I entirety, consisting of thetwo parts A and B.

The part A" or body portion is shaped as shown in the drawings, having the semicy lindrical portion 6' for engagement with. the usual penholder. The fiat portion 7, with tapering or wedge-shaped portions 8 8, is ar-' ranged to receive the removable plate B, which when in position forms an ink-reservoir 9. The lower edge of the plate B is Application filed April 12,1906, smart. 311.274.

arallel with the lower edge of the portion 7,

eaving .a fine slot or opening 10 for the flow of ink. The'upper portion of the plate B is curved-down upon the ortion 7, forming a closure at this point. I t this end of the plate 13' a small orifice 12is cut, through which the ink is supplied to the reservoir.

In cutting the orifice 12' a slight projection 13 is formed forthe ready manipulation of the plate B. At each side of the open- .ing or mouth 10 are arranged small points or projections 14 14 to arrest any side flow of the ink and insure a sharp clear-cut line in marking. In the lower edge of the portion 7 (see Fig. 5) small notches 15 are cut, which might be termed rimingoints to insure aready flow of in r. A sight recess 16 is formed in the part A to receive the upper edge of the plate 12, thus sealing the reservoir at this point and preventing the ink from escaping when the pen is in the position shown in Fig. 1.

To insure an even flow of ink, a small piece of paper or fabric 17 (see Fig. 3) is placed in the reservoir 9 with its lower edge projecting differ only in configuration from that'shown in Fig. 1, while the form shown in Fig. 1 broadens as it reaches the point or mouth 10.

The form shown in Fig. 7 has parallel sides and the form shown in Fig. 8. has inwardlyprojecting sides contracting the mouth 10.

In operation the pen is filled with ink with the usual ink-dropper used in filling fountain-pens, the ink being introduced through the orifice 12. The pen being now ready for use'is susceptible of all the various markings, shading, and embellishing common to this class 'of' marking-pen, and a sharp clean-cut line is always assured by reason of the projecting points 14. These points 14 also enable other designs to be executed by swinging a half-radius alternately resting on one point, then the other, turning the pen in opposite directions.

IIO

It will be seen that a pen constructed as above may be made of comparatively stiff sheet metal, forming a rigid marking-pen that may be used on almost any surface.

The body portion A might terminate in a large sleeve, forming a holder, in place of the engaging portion 6 without departing from the spirit of my invention.

Having thus described my invention, what 1. In a marking-pen of the character described, the combination of a body portion provided with a removable plate forming a reservoir having an elongated mouth for the flowof the ink, the pen being provided on opposite sides of its mouth with small points or projections for the purpose set forth.

2. In a marking-pen of the character described, the combination of a body portion provided with a removable plate forming a reservoir for the reception of the ink, the lower edge of said plate cooperating with the lower edge of said body portion to form an elongated mouth for the flow of ink, the upper edge of said plate being turned inwardly forming a closure to the reservoir at this point and provided with an orifice cut in said plate for the introduction of the ink to the reservoir, substantially as shown and described.

3. In a marking-pen of the character described, the combination of a body portion provided with a removable plate forming a reservoir having an elongated mouth, the body portion terminating in two projections one on each side of said mouth, substantially as described.

4:. The herein-described marking-pen consisting essentially of a body portion provided with a removable plate forming a reservoir having an elongated mouth, the body portion also having side'ledgcs and a transverse recess for holding the plate in place, the said plate having an orifice for the introduction of the ink, and a projection for the ready manipulation of the said plate, the said. plate being rigidly connected with the body portion to prevent the enlargement of the mouth during use.

In testimony whereof I aflix my signature in presence of two witnesses.
